Hello,

starting with KMail from KDE 3.5.6 I often get crashes when filtering many=
=20
messages in a folder manually (applying all filters).
The problem goes down to the following lines in kmfolder.cpp:

int KMFolder::find( const KMMsgBase* msg ) const
{
  return mStorage ? mStorage->find( msg ) : 0;
}

I've encountered mStorage being null, so I end up with 0 in the calling met=
hod=20
KMHeaders::applyFiltersOnMsg() (in kmheaders.cpp line 1378).

      int idx =3D msgBase->parent()->find(msgBase);
      assert(idx !=3D -1);
      KMMessage * msg =3D msgBase->parent()->getMsg(idx);

If I insert a condition to process only for idx !=3D 0, KMail doesn't crash=
=20
anymore.
This makes me wonder if idx =3D=3D 0 is a valid index and how the assert is=
 meant=20
to work. Of course, the real problem is mStorage being not defined, but=20
that's a bit beyond my knowledge of the folder stuff in KMail.

Well, if someone can comment on this, I'd like to fix it the right way.

Regards,
Andreas
